I have a well taken care of agm fuzion TM35-640LRF monocular. This has spotted many many mice and without it I would have never seen them. A monocular amd NV combo is a killer setup and the 640 resolution is amazing. It works as it should and if you have any questions just ask. $2000 and it's yours the LRF is a great thing since you can't range in the dark with a traditional rangefinder this is built in and shows right on the display.
